Iran's Foreign Minister, Mohammad Javad Zarif, said the country will look into finding other solutions to the demands made by Western countries that they provide access to U.N. inspectors as they look at their military sites and interview their nuclear scientists.

Iran's reluctance to sign off on granting complete access to nuclear sites and personnel came after a long six-hour marathon of meetings held together with U.S. Secretary of State John Kerry.

Granting access to international inspectors has not been something Iran has been willing to give out, and now, it could potentially endanger a nuclear agreement between Iran and six other countries, according to Reuters.

Western officials continue to insist that allowing the U.N.'s International Atomic Energy Agency to inspect their nuclear facilities needs to be part of any comprehensive agreement that could be forged between the two sides. 

The head of the U.N.'s atomic watchdog, Yukiya Amano has also indicated that any deal Iran will sign together with the other world powers will include granting permission to the inspections, according to Al Jazeera.

Iran remains resistant to the idea, even adding that they have no ambition to develop any nuclear weapon and that there is no clandestine nuclear program working in the shadows.

As for how Iran plans to work around the issue of the inspections, Zarif has yet to give details about a possible solution, and he also added that there were still several points of contention aside from the nuclear issue which could potentially end the agreement.

Another sticking point blocking the way of a potential agreement being finalized is related to a possible mechanism which could put sanctions on Iran back into place the second the country is found in violation of any of the rules outlined in the deal, according to The Jerusalem Post.

For now, what appears obvious is that both Iran and the other world powers involved in the discussions still have fundamental issues to talk about if any deal between the two sides will ever be put in place.
